refactor(core): Consolidate binary file not found errors (no-changelog) (#7585)

Logging was originally to see if there was a binary data file failing to
be written for [this
user](https://linear.app/n8n/issue/PAY-844/filesystem-binary-data-mode-causing-alerts-in-cloud)
but the cause was not a file failed to be written but a missing `fileId`
in a binary data item in an execution. The error should no longer be
thrown as of 1.12. See story for more info.

This PR is for cleanup and to consolidate any file not found errors in
the context of binary data, to track if this happens again.
